Autoblog editors choose their favorite racecars of all time

If you like cars, there is a good chance that you like racecars. There's something about the science and the art of going faster, of competition, of achievement, that accelerates the hearts of enthusiasts. It doesn't matter the series, the team or the manufacturer – there's something about racing that stirs emotions and lifts spirits. It's that way with many of you, and it's that way with our editors. With that in mind, we offer a list of our favorite racecars of all time. Of course, we'd like to hear some of yours in the comment section below. 1970 Porsche 917 Compared to some of the obscure choices by my colleagues, I feel like the Porsche 917 is almost so obvious a pick as to not be worth mentioning. Still, when coming up with my answer, my mind invariably went back to this classic racer – specifically in its blue-and-orange Gulf livery – while watching Le Mans on DVD and later Blu Ray with my dad. Long, low and curvaceous, few vehicles have ever looked sexier lapping a track than the 917. More than just a pretty face, this beauty had speed, too, thanks to several tunes of flat-12 engines over the course of its racing life. In the early '70s, Porsche was a dominant force throughout sports-car competition, and the 917 (shown above at the 1970 24 Hours of Daytona) was the tip of that spear, including back-to-back victories in the 24 Hours of Le Mans. Largely without dialogue or really much of a traditional plot, Le Mans is like a tone poem of racing goodness. While the 917's importance to motorsports history is undoubtedly fascinating, it's still this cinematic depiction of the Porsche racer that draws me in most, especially with the volume cranked. – Chris Bruce Associate Editor 1964 Mini Cooper S How could everyone not be selecting the 1964 Mini Cooper S piloted by Paddy Hopkirk and Henry Liddon? That car, 33 EJB, took the first of British Motor Corporation's four Monte Carlo Rally wins (it should have been five, but French judges got the British Minis [and Fords] disqualified on a technicality regarding headlights... which its own car, the winning DS, was also in violation of). The tiny red car and its white roof beat out Ford Falcons, Mercedes-Benz 300SEs and scores of Volvos, Volkswagens and Saabs. This, along with the several years of dominance that followed, cemented the idea that not only could the tiny, two-tone Mini be a real performance vehicle, but that family-friendly city cars in general could be fun.

Audi re-illuminates Sport Quattro with Laserlight concept for CES

Automakers typically spend months working on a concept car, then unveil it at a car show and move on to the next. But Audi has demonstrated a propensity at refining the same concepts and bringing them back for more. Just look at how many time Audi iterated its E-Tron concept, and how many diesel R8s it toyed with. It brought the Italdesign Parcour out of retirement and rechristened it the Audi Nanuk, and it's been doing the same with the Quattro concept for the past several years. The German automaker rolled out the first Quattro concept back in 2010, and followed up with the reborn Sport Quattro concept less than a year ago. And now it's preparing to unveil yet another.
Called the Sport Quattro Laserlight concept, this time it's not as radical a departure from the Sport Quattro concept as that was from the first Quattro concept. In fact, there's really only one vital difference. That'd be the laser headlights "that leave all previous systems in the dark," according to the press release below. The system uses matrix LEDs around the outside of the element as low beams, and lasers on the inside for high beams. Measured in mere microns, the laser diodes are significantly smaller than LEDs, while lighting up the road ahead for nearly half a kilometers (1,640 feet), providing twice the lighting range and three times the brightness of LED high beams.
Otherwise the concept car you see here and which Audi will display at the Consumer Electronics Show in Las Vegas next week is essentially the same as the one it showed in Frankfurt this past September. It's got the same measurements, wearing the same CFRP bodywork, with the same interior and the same 700-horsepower hybrid powertrain, only the yellow exterior has been repainted Plasma Red and the black interior redone in a more low-key Slate Grey, as you can see from the high-res image gallery above.

Audi pits S3 against Ur-Quattro on gravel

If you had to pick a winner between the latest Audi S3 and the original Audi Sport Quattro, which would it be? Both hot hatches pack around 300 horsepower and all-wheel drive, but they're separated by a good thirty years of development.
To find out, Audi took both to the old rally circuit in San Remo. Behind the wheel of the Ur-Quattro they put none other than The Stig himself - no, not the Top Gear test bot, but Stig Blomqvist, the Swedish former rally driver who drove the Quattro to the World Rally Championship in the mid-80s. In the S3 they put someone named Hermann Müller, who as best we can tell was one of Auto Union's original Silver Arrow drivers - but he died in 1975, so it's probably the guy who writes for the Audi magazine. Regardless, the contest was pretty close, so it's worth checking out in the 2:26 video clip below.
